Title: An installation including a steam boiler
IPC: F22B35/06
Filed: 1968-03-14
Abstract: 1,216,524. Controlling and indicating furnace conditions. SIEMENS A.G. 14 March, 1968 [15 March, 1967], No. 12557/68. Heading F4B. An arrangement for controlling the fuel supply system either manually or automatically of an installation including a steam boiler comprises ascertaining the momentary limits to any variation in load on the boiler which are regarded as allowable and taking into account the speed at which such variations can be carried out without damaging the boiler, the arrangement being such that the essential criteria governing permissible variations of the fuel supply are subjected to continuous monitoring thereby. An analogue unit calculates the maximum permissible load variations and temperature limits and signals representing these values are fed to a time delay unit wherein they are plotted in accordance with a curve showing the relationship of output to input of the boiler. The arrangement therefore will change the limit normally set to the demand signals and also the speed at which can be answered in accordance with the conditions existing both at that time and having a previous history of being possible without boiler damage.

Abstract: 886,513. Thermonuclear apparatus. UNITED STATES ATOMIC ENERGY COMMISSION. April 14, 1959 [May 23, 1958], No. 12589/59. Class 39(4) Thermonuclear apparatus comprises an evacuated space to which charged particles are supplied, magnetic field means for generating a travelling wave magnetic field progressing through the space with the alternate maxima and minima of the magnetic field defining a continuous series of moving magnetic containment zones for containing charged particles, the magnetic field spatially varying in intensity in the direction of wave motion to vary the energy of charged particles contained within the zones, and particle injection means disposed within the space to introduce charged particles into the moving containment zones. In Fig. 1 the container 11, which may be of thin stainless steel or borosilicate glass, is generally cylindrical with flared ends and is evacuated to a high degree by pumps and cold traps attached at each end. The container is surrounded by coils 21, the spacing between which decreases from the left towards the centre and then increases towards the right. The coils are energised by a D.C. biased A.C. source means to produce a travelling magnetic wave having a D.C. component which increases sharply in the first section of the container, increases more gradually in the middle section, and decreases sharply at the end section. The coils may he energised by a plurality of D.C. generators 23 mounted on a common shaft driven by a motor 24. The field windings 28 of the generator may be connected as shown to a three-phase A.C. supply 32 of several cycles per second so that a slowly varying A.C. component is superimposed on the D.C. component to produce the travelling magnetic wave. The D.C. component may be adjusted by resistances in series with the coils or by varying the turns density of the coils in accordance with their axial position. In operation fuel plasma is injected at a small pitch angle from injectors 41 and is carried along the container by the travelling magnetic wave. In the first section of the tube the D.C. field increases and compresses the plasma adiabatically; in the second section there is an adiabatic radial compression and axial decompression caused by the increased D.C. field and the greater spacing between coils 21, finally there is an expansion section where the field decreases where energetic reaction products expand against the field and induce currents in coils 21 causing some of the generators 23 to act as motors driving the others and delivering usable electricity from motor 24 acting as a generator. Specification 821,744 is referred to.

Title: Steam generating plants which employ electric motors
IPC: F01K17/00
Filed: 1953-05-11
Abstract: 721,099. Electric fluid heaters. SULZER FRERES SOC. ANON. May 11, 1953 [May 14, 1952]. No. 13120/53. Class 39 (3). In steam generating plants employing electric motors for driving auxiliaries such as pumps and blowers and regulated by control resistances 1-4, these resistances serve as heaters for a fluid employed in the plant, for generating or superheating steam, for pre-heating feed water, furnace air or liquid fuel. The control resistances comprise immersion heaters or electrode boilers. In the figure, the broken line shows the path of the water and the thick continuous line that of the steam. Feed water is supplied by a pump 10 from a vessel 9 to a boiler 5 supplying steam to a turbine 6 driving a power absorber 7 such as an electric generator. Steam from the turbine is condensed in a condenser 8, whence water flows to the feed vessel 9. Immersion heater 1 in a small boiler generates steam supplied to the boiler 5 through a water separator 11. Heater 2 is supplied with water tapped off from a secondary feed water pipe and provides low pressure steam injected into the secondary steam pipe pipe leading from the condenser 8. Heater 3 vaporizes. and superheats condensate in the closed circuit of the secondary steam superheater 12. Heater 4 pre-heats combustion air for the boiler 5. In using water as the control resistance in an electrode boiler, the distance between the electrodes may be adjusted and the current may flow through water jets divided against one electrode from nozzles in a counter-electrode. An asynchronous motor may drive an induced draught blower producing a subatmospheric pressure in the combustion chamber, the speed of the motor being adjusted automatically in dependence on the adjustment of a flue gas valve on the pressure side of the blower. A slip ring motor may be used for the high pressure feed pump. Control resistances of two or more motors may be incorporated in the same heater.
